FERDINAND BARRE, oF BALTIMORE?, MARYLAND, AssIeNoR To ARMORED CONCRETEy CONSTRUC'iIOll COMPANY OF BALTIMORE CITY, A CGRPORATION OF CONCRETE BEAM.

To all whom it may concern:

Be it known thatl, FEnDrNANo BARR, e. citizen of the United States, residing at Baltimore, in thc State ot Maryland, have invented new and useful Improvements in ileinforcemenis for Concrete Beams, of which the following is a specication'.

This invention relates to improvements' in reinforcements for concrete beams, such as shown arid described in Letters Patent o the United States, dated February 2, i90-l, No. 751,427.

The object oi the invention is to provide a cheap, simple, and efficient means for the reinforcement of beams constructed of concrete or other similar material..

Other features of the invention will be fully setforth in the accompanying specification and pointed out in the claims. f

in the accompanying lrawings,--Figure l is a side elevation oi a portion of a beam resting on one column and having one end projecting into the masonry or side wall, the concrete being omitted. Fig. 2 an inverted plan View of Fig. 1, the large lower rods being broken away. Fig. 3 is a. vertical sectional .View on the line of Fig. l.. Fig. 4 is a vertical sectional view on the line y-y or' Fig. l.. Figs. 5, G, and, 7 are detailed vviews of one of the stirrups, showing the position of the bars that rest in the lower` end and 'the bars that project through the upper end thereof. A i

Similar reference-num erals designate like parts throughout the several views oi the drawings.

Referring to the accompanying drawings, ormingiy part of this specification, i designates the concrete beam,y 2 the masonry or side wall, and 3 one-'of the columnsr The stirrups 4 are formed of; metal or other suitable material, the ends being irst bent downwardly and, then upwardly, forming the bend 5 ht the upper end. and the two bends G at the lower end, the extremities terminating on a. plane with the upper bend. 5. The bends G at the lower end are at right angles to the bend 5 at the upper end. The extremities and the upperbend 5 of the stirrup 4 diverge to form a wide openingl to therods 7, 8 and 9 when they are being placed in the 'said stirrups. These stirrups 4 are placed along the beams in rows, in the present instance two rows, as seen in Figs. 2 and 3, at a suitable distance apart. The straight rods 7 rest in the lower lends of the stirrups of each row and have one end projecting into the masonry and the other ond resting over the column 3,oreacl1 end lol the rod 7 may rest over a column. Two rods 8 and t 9, which are somewhat smaller in diameter than the rod '7, rest in each row of the stir-rups 4 above the rod 7 and one oi' said rods 8 has one end resting above the column 3 and the other end extending upwardly onan incline Speceation of Letters Patent, Application met Janusryeo, 1906. solo No. 297.938.

.-1 at l0 and projecting into the masonry 2 vnear the top ofA the beam, and the otherrod 9 in the same row of stirrups has one end projecting into the masonry 2 and the 55 oppositeend extending upwardly on an incline at il' and projecting over` the column 3 near the top of the beam. There are always two rods 8 and 9 in eachrrew 'of stirrups above the rod 7, one of said rods 8 projects l upwardly at one end to near the top of the beam and terminates just beyond one of thecolumns and the other rod 9 in the-same row of strrups projects upwardly at the opposite end to near the top ofthe beam and terininates just beyond on'e ofthe columns, theupwardlyi projecting ends of the rods 8 and`9 lieadjacent, and pro- .65" ject beyond, each other over each column. The rods l2 project through the upper ends of thostirrups 4 at right angles to the rods 7, 8 and 9 and extend from one` beam to another throughthe iloor 13, as shown lin Figsf l 1,2 and 3Q Afterthe stirrups 4 and rods 7,"8, 9 and l2 i7() are placed in position the concrete or other material is f liiled in and the beam formed to any desired shape.

Having thus described my invention what I claim iszj L l. The combination with :1 beam formed or' concrete-orj7`5 other suitable material, or' two -rows of stirrups 4, a sti-aight rod resting in the lower ends or' the strrups-i of cach row and projecting over two-columns, and two rods s 25 :1nd 9`in each row of stirru above the rod 7, one of said rods S projects upwardl5Y at one end to near the top .8(1 i of the beam and terminates just beyondbne ot the col; unms and the other rod :'liu the same rowot `stirrupspro-i` jects upwardly at the opposite endjoneal' the `top`o the beam and terminates justybeyomlon'lx iof\ th`e-columns`the upwardly-preisetingend of. the i'otls lS'andxQQlie adja`eent,"` 85- land project beyond; each other over each column;
